The aim of the present study was to examine the movement patterns, ball skills, and the impressions of Swedish elite football players during competitive games on artificial turf and natural grass. Time - motion analyses (36 observations) and technical analyses (16 team observations) were performed and 72 male and 21 female players completed a questionnaire. No differences were observed between artificial turf and natural grass in terms of total distance covered (mean 10.19 km, s = 0.19 vs. 10.33 km, s = 0.23), high-intensity running (1.86 km, s = 0.10 vs. 1.87 km, s = 0.14), number of sprints (21, s = 1 vs. 22, s = 2), standing tackles (10, s = 1 vs. 11, s = 1) or headers per game (8, s = 1 vs. 8, s = 1), whereas there were fewer sliding tackles (P < 0.05) on artificial turf than natural grass (2.1, s = 0.5 vs. 4.3, s = 0.6). There were more short passes (218, s = 14 vs. 167, s = 12) and midfield-to-midfield passes (148, s = 11 vs. 107, s = 8) (both P < 0.05) on artificial turf than natural grass. On a scale of 0-10, where 0 = "better than", 5 = "equal to", and 10 = "worse than", the male players reported a negative overall impression (8.3, s = 0.2), poorer ball control (7.3, s = 0.3), and greater physical effort (7.2, s = 0.2) on artificial turf than natural grass. In conclusion, the running activities and technical standard were similar during games on artificial turf and natural grass. However, fewer sliding tackles and more short passes were performed during games on artificial turf. The observed change in playing style could partly explain the male players' negative impression of artificial turf. 相似文献

This study investigates continuing professional development (CPD) of vocational teachers, with a focus on recurrent participation. Vocational teachers need to be competent as teachers and in relation to their vocational teaching subject. Reformation of Swedish vocational education in order to strengthen the working-life connection imposes demands on teachers to have up-to-date knowledge about the vocations related to their vocational subjects. To support the reform, vocational teachers have been offered to participate in a new national CPD initiative targeting their vocational competence. The study concerns participation in this initiative. Drawing on a socio-cultural perspective, vocational teachers’ CPD implies boundary-crossing between school and working-life. Theory concerning adults’ participation in education is considered relevant to understand conditions for such boundary-crossing, and learning, among vocational teachers. The article specifically investigates patterns in vocational teachers’ recurrent participation, which is expected to clarify the factors influencing further participation in professional development. The strongest predictor of recurrent participation, when adjusting for the influence of other factors, is the type of municipality that the teacher comes from, with low populated municipalities having the lowest likelihood of participation. Furthermore, recurrent participation is more likely by participating teachers from adult education or from privately owned schools, and by male teachers. 相似文献

Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations.Purpose: The purpose of the research was to explore students’ interactions with reformed thermodynamics laboratory activities. It was guided by the research question: How do university physics students make use of IR cameras in open-ended investigation of thermal radiation as a phenomenon?Sample: The study was conducted with a class of first-year university physics students in Sweden. The interaction with the activities of four of the students was selected for analysis. The four students are males.Design and methods: We used a qualitative, interpretive approach to the study of students’ interaction. The primary means of data collection was video recording of students’ work with the laboratory activities and their subsequent presentations. The analysis focused on how IR cameras helped students notice phenomena relating to thermal radiation, with comparison to previous research on students’ conceptions of thermal radiation.Results: When using the IR camera, students attended to the reflection of thermal radiation on shiny surfaces, such as polished metals, windows or a whiteboard and emissive properties of surfaces of different types. In this way, they went beyond using the technology as a temperature probe. Students were able to discuss merits and shortcomings of IR cameras in comparison with digital thermometers.Conclusions: With the help of IR cameras, university physics students attend to thermal phenomena that would otherwise easily go unnoticed. 相似文献

One aim of student evaluation of instruction is the improvement of teaching quality, but there is little evidence that student assessment of instruction alone improves teaching. This study tried to improve the effects of evaluation by combining evaluation with individual counselling in an institutional development approach. Evaluation was conducted in a private school for speech therapy (logopedia) in 35 classes (N = 16 teachers, N = 592 students). Evaluation was done twice within a period of three to twelve months using a standardized questionnaire (HILVE‐II) developed for evaluation of university courses. The intervention effect on teaching quality was more than half a standard deviation on the teacher scales. Despite the fact that the counsellor had no pedagogical training, the quality of teaching not only improved quantitatively and qualitatively but also became more homogeneous although the relative rank listing of teachers did not change. Ein Ziel der studentischen Lehrevaluation ist die Verbesserung von Lehrqualität. Es gibt aber wenig empirische Evidenz dafür, dass studentische Lehrevaluation allein Lehre verbessern kann. Diese Studie versuchte, die Effekte von Veranstaltungskritik in einem Ansatz, der Lehrevaluation mit Beratung verbindet, zu erhöhen. Lehrveranstaltungsevaluation wurde in einem privaten Ausbildungsinstitut für Logopädie in 35 Kursen von 16 Dozenten mit 592 Studierenden durchgeführt. Veranstaltungskritik wurde zweimal praktiziert binnen eines Zeitabschnitts von drei bis zwölf Monaten anhand eines Fragebogens (HILVE‐II), der für die Evaluation von Hochschulveranstaltungen entwickelt wurde. Der Verbesserungseffekt auf Lehrqualität war in den dozentenbezogenen Skalen größer als eine halbe Standardabweichung. Obwohl der Berater keine pädagogische Ausbildung hatte, verbesserte sich die Lehrqualität nicht nur in den quantitativen und qualitativen Maßen, sondern wurde auch homogener. Die relative Rangreihung innerhalb der Dozenten blieb aber stabil. Un des objectifs de l’évaluation, par les étudiants, de l’enseignement est l’amélioration de la qualité de ce dernier. Pourtant, les preuves que l’évaluation de l’enseignement par les étudiants améliore celui‐ci sont limitées. Cette étude a tenté d’améliorer les effets de l’évaluation en combinant l’évaluation avec du conseil individuel au sein d’une approche de développement institutionnel. L’évaluation a été effectuée dans 35 classes (N = 16 enseignants, N = 592 étudiants) d’une école privée d’orthophonie (logopédie). L’évaluation a été effectuée deux fois sur une période variant de trois à seize mois en employant un questionnaire standard (HILVE‐II) développé pour l’évaluation des cours universitaires. L’effet relatif à la qualité de l’enseignement associé à l’intervention représentait plus d’un demi écart‐type sur l’échelle des enseignants. En dépit du fait que le conseiller n’avait pas de formation pédagogique, la qualité de l’enseignement s’est améliorée à la fois au plan quantitatif et au plan qualitatif, en plus de devenir davantage homogène, bien que le positionnement relatif des enseignants n’ait pas changé. 相似文献
